摘  要：差壓變送器是測量變送器兩端壓力之差的變送器。測量介質(zhì)正負(fù)兩端的壓力差，轉(zhuǎn)化成可以反應(yīng)壓力差的標(biāo)準(zhǔn)電流信號（4-20mA）�，F(xiàn)著重介紹EJA差壓變送器的工作原理，對EJA差壓變送器實際應(yīng)用中導(dǎo)致除氧器液位調(diào)節(jié)器指示波動的故障進(jìn)行分析處理，消除了故障癥結(jié)。 關(guān)鍵詞：差壓變送器  調(diào)節(jié)閥  調(diào)節(jié)器  故障 Abstract: The differential pressure transmitter is a transmitter that measures the difference in pressure across the transmitter.
